Trigger Maru has incorporated the core aspects of “Environmental mod version 5.0”, some elements of
the “Real Environments mod.”, and some of it's own tweaks to come up with a someone unique
environment. This have been done to ensure that other core aspects of TMO work properly.
Installing another Environmental mod over TMO is not recommended
I would recommended trying to message or find threads from Ducimus to find out what files to look at.
